    Hi there,

    my name is Stefan. In 2016 I bought an BQ Aquaris M10 tablet - which worked well with Ubuntu Touch (given my use case). However, it has reached end of life. During the last two years I played around with Pinetab2, but the result was somehow cumbersome, and low performant.

    Recently I bought a used Lenovo TB-X306FA. I followed the installation instructions, but with my computer (Asus / Ubuntu 24.04) the SP_Flashtool was not capable to update Android. Hence I followed thecosmix UT_Install_ReadMe.md instructions to flash via fastboot, resulting in a device with Android 11. Then I utilized the UBports-Installer. The Lenovo-device works perfectly so far. Thanks to everybody who contributed!

    Regards, Stefan

  • RE: ut-sysbench-qt-gui: Compare CPU performance of different devices

    I used the test for 3 devices, here are the results:

    1. Device BQ Aquaris M10 FHD, Ubuntu 16.04

    sysbench --test=cpu --num-threads=2 --Cpu-max-prime=20000 run 59 events per second

    sysbench --test=cpu --num-threads=8 --Cpu-max-prime=20000 run 113 events per second

    sysbench --test=memory --num-threads=4 run Operations performed: 0 ( 0.00 ops/sec) 0.00 MB transferred (0.00 MB/sec)

    sysbench --test=mutex --num-threads=64 run total time: 0.9229s

    1. Device xperia X ubuntu-sdk-20.04

    sysbench --test=cpu --num-threads=2 --cpu-max-prime=20000 run 1385 events per second

    sysbench --test=cpu --num-threads=8 --cpu-max-prime=20000 run 2465 events per second

    sysbench --test=memory --num-threads=4 run Total operations: 25487419 (2546616.80 per second) 24890.06 MiB transferred (2486.93 MiB/sec)

    sysbench --test=mutex --num-threads=64 run total time: 9.2790s

    1. Device: pinetab2, ubuntu-sdk-20.04

    sysbench -test=cpu -num-threads=2 -cpu-max-prime=20000 run 678 events per second

    sysbench -test=cpu -num-threads=8 -cpu-max-prime=20000 run 1263 events per second

    sysbench -testzmemory -num-threads=4 run Total operations: 50881276 (5086734.72 per second) 4968.75 MIB transferred (4967.51 MiB/sec)

    sysbench -test=mutex -num-threads=64 run total time: 15.9498s

    This result is quite in line with my observations when using these devices: Xperia X performance is quite good after the update to the new release.

    Kind regards, Stefan
